Despite sharing the record of 11 FA Cup wins with Arsenal, United haven’t lifted the trophy since 2004. Sporting Index have them trading as joint-second favourites on the FA Cup Outright Index at 46-50, alongside Manchester City, with Chelsea the 49-53 leaders.
Points are awarded as follows: winner = 100pts, runner-up = 70pts, lose semi-final = 50pts, lose quarter-final = 33pts, last 16 = 20pts, last 32 = 10pts. Buyers of United at 50 would need the Red Devils to reach the final to return a profit.
It might pay to take a chance on a lesser-fancied side. West Ham have shone in the league, and showed guts in the last round when beating Everton 9-8 in a dramatic penalty shoot-out.
The Hammers are pitched at 25-28. They have a winnable tie with Bristol City on Sunday and, granted luck with the draw, could go well. Buyers would make a profit of five times their stake even if they are beaten in the quarters. But if City defeat them then buyers would lose 18 times their stake.
